PopCap is staging a charity event on Tuesday, June 26th to help benefit charity: water, and to set a Guinness World Record. Two women, Kathleen Henkel playing at the Roger Smith Hotel in New York City and Laura Rich playing at the SEA LIFE London Aquarium, will try to play the game for 24 or more hours of Solitaire Blitz to set the record for Longest Videogames Marathon Playing a Card Game. They can take breaks while playing, but the rules are very strict about how long their breaks can be.

PopCap is pledging $5,000 for each player, and individuals can pledge money for each hour that the two women play on the Solitaire Blitz Facebook page. Their attempts to set the record can be viewed live on the internet starting at 2:00 PM GMT (9:00 AM EDT), or in person at each location, where PopCap will be handing out free goodies, and taking donations for charity: water.
